Melatonin is a hormone, also known as N-acetyl-5-methoxytryptamine, which is made by the pineal gland, at the center of the brain in humans and animals.
It can also be found in microbes and plants. This hormone helps control your wake and sleep cycles.
It can be found in small amounts in foods such as vegetables, fruits, grains, and meats. Also, you can buy it as a supplement.
